Description peterp 2001-10-16 13:21:17 UTC 
Build 011015_2 (trunk). When trying to set breakpoint in JSP I receive this 
exception:

Breakpoint is not set. Tried on Windows 98 with JDK 1.3.1b-24 and Windows 2000 
with JDK 1.3.1_01.

Moving to debugger module.
Comment 2 Daniel Prusa 2001-10-17 11:04:07 UTC 
Is it possible to reproduce this exception reliably ? (Trying it, I 
have not been successful.) If so, can you describe the needed steps 
in details, please ?
Comment 3 peterp 2001-10-17 12:12:23 UTC 
Even in current build:

1) have JSP with this content:

<%@page contentType="text/html"%>
<html>
<head><title>JSP Page</title></head>
<body>

<%-- <jsp:useBean id="beanInstanceName" scope="session" class="package.class" /> --%>
<%-- <jsp:getProperty name="beanInstanceName"  property="propertyName" /> --%>
aaa
<H1> bb </H1>
<H2> ccc </H2>
</body>
</html>

2) go to <H1> line
3) press Shift-F8

That's it.
Comment 4 Daniel Prusa 2001-10-17 15:02:15 UTC 
NPE fixed in main trunk.
Comment 5 Jan Stola 2001-10-19 14:45:16 UTC 
Verified in Netbeans build 20011019.
Comment 6 Quality Engineering 2003-06-30 17:31:06 UTC 
Resolved for 3.3.x or earlier, no new info since then -> closing.
